Mound System : A mound system is one of the most common septic systems and they are frequently used in areas with high water tables of shallow bedrocks. It uses an elevated mound of sand as the drain field, afterwards, the septic tank pumps the waste into the drain field in small amounts. From there, it´s filtered through the sand and distributed into the native topsoil.

Recirculating Sand Filter System : Sand filter septic systems are basically large PVC- lines or concrete boxes filled with sand. A pump pushes the waste through the top layer of sand, where the system treats and filters the wastewater. And finally, the system scatters the wastewater through the drain field.

Aerobic System : The oxygen inside the aerobic treatment unit speeds up the bacteria activity along with the waste to break down efficiently. Aerobic systems might also require pre and post treatments tanks to get rid of bacteria before it spreads into the drain field.
